I had just enough backing on this quilt with about 1/2 inch to spare.
This wouldn't be a problem if I was quilting from the front of the machine, but I was doing a panto from the back. I usually mark the edge of the quilt on the table with masking tape so that I know about how far to quilt and I actually stitch off the top just a bit and then back on, like this.
I knew that there wasn't any room to do that on this one, so I marked the table with masking tape and then re-drew some of the lines with a dry-erase marker so that I wouldn't be going off the quilt. This is something I do frequently at the edge of a quilt so that the design doesn't seem too fragmented but I had never done it to this extent. A word of caution here - make sure you wipe the marks off your table before you unload your quilt.
Here is the last row of the design and I really like the looks of it. I may be doing this more often.
